Which inflorescence type is characterized by unlimited growth?

• A. Cymose
• B. Basipetal
• C. Acropetal
• D. Racemose

Answer: (D)

Unlimited growth means the main flowering axis keeps lengthening and continues to produce new flowers along its length. This is the hallmark of racemose inflorescences, where the axis keeps growing and new floral buds appear along it, so the bloom sequence can extend indefinitely as the plant keeps pushing new growth upward. In cymose inflorescences, growth is finite because the terminal flower ends the axis, and additional flowers arise from lateral buds, not by further elongation of the main stem. Basipetal and acropetal describe the direction of flower maturation along the axis (which end blooms first), not the overall growth pattern, so they don’t indicate unlimited growth.
